For many OEMs, electronic systems are expected to remain in service for years — sometimes decades. Over time, however, maintaining these systems becomes increasingly challenging. Components become obsolete, failure rates increase, and support costs continue to rise. When a PCB assembly begins to fail, manufacturers face a critical decision: 👉…

What Is EMI in PCB? Electromagnetic Interference (EMI) in PCB design refers to unwanted electromagnetic noise that disrupts signal integrity and affects circuit performance. EMI can either be emitted from your PCB or received from external sources. In high-speed and RF designs, poor EMI control can lead to: Signal distortion…

What Is PCB Impedance Mismatch? PCB impedance mismatch occurs when the characteristic impedance of a transmission line (trace) does not match the impedance of the source, load, or adjacent interconnects. This mismatch causes part of the signal to be reflected back toward the source instead of being transmitted efficiently. In…
